housing containing lubricant which has boltedto its rear wall 2 .a supplementary housing for theadjustnient and safety mech: anism, designated It is attached by the bolts 4- to thehousing 1. A suitablecov Thee lower end of.:tl1e main" housing 1 1 is provided with the tapered roller bearing 6 for receivingthe driven shaft 7 This shaft is retained in position at its upper end by the roller bearing 8, which'is carried by the'cover plate 5. *Onthe driven shaft is mounted a suitablecrank 9 for attachment to the stoker arm or equivalent mechanism, which is tolbe driven in conjunction with the driven shaft 7.

-- The shaft 10, which isfsupportedhorizon tally; 111 the casmgl, carries a worm 11 that ien ages with a worm .gear' 12. y This worm gear isbolted bythebolts13on to a plate 14 of a. sleeve 16 that turns freely upon the driven shaft 7 The sleeve 16 carries an elongatedhmar' 17. The 1 sleeve is supported on v the rollerbearin zs 18; the outer face of which rests upon the shoulder 19 ofthe planetary gear carrier 20. The shaft 10, motor 10 worm 11, gear 12, sleeve 16 and its gear 17 rier2O operatesintermittently. 1

l flcmetary gearfcarrier The planetary gear carrier isjprovided with a plurality of vertically-disposed"shafts 21,

which carry planetary freer pinion-s 22 that mesh with the gear 17. These gears also mesh with a ring or orbit gear -23 which is carried on a ring gear carrier 24. The'ring gear carrier rests upon the ends of the gears This completesthe planetary gear mechanism. 3 v 5 The ring gear carrier 24 is provided with an eccentric cam 25 whichoperates the setturn continuously. The planetary gear carting mechanismfor determining the period of the cycleof operations of the mechanism.

Thering gear carrier also carriesthe ring gear carrier disc 26, Which engages with a ring gear carrier release] arm, the operation of which, when in engaging position, is to hold stationary the ring gear carrier.

Planetary gear carrier operating mechanism The planetary gear carrier has a cam 27, known as a reset cam. which serves to reset the mechanism, hereinafter described, that eventually stops the planetary gear carrier. The planetary gear carrier also carries a disc 28 which is utilized to stop in conjunction with the holding arm the planetary gear carrier and thereby bring to rest the driven shaft 7 to which the planetary gear carrier is attached by the key 29.

This disc 28 is provided with a depression 30 which receives the roller 31 on the planetary gear carrier holding arm 32. This arm 32 is provided with a laterally extending shoulder 33 for receiving a returning spring 34, the other end of which at 35 is mounted on the inside of the casing l. The arm 32 carries an upwardly projecting lug 36, the function of which will be hereinafter explained. The arm 32 is mounted by a key 37 on shaft 38 known as the re-set shaft.

Re-set mechanism This re-set shaft carries on it loosely a sleeve 39 which supports a laterally-extend ing re-set arm 40 carrying a roller ll that is engaged by the arcuate cam face 42 of the re-set cam 27. It rolls upon the face 43 for a period before dropping off and descending along the face 44. The arm 40 is pro vided with a depending lug 45 that engages the lug 36 on the arm 32. The sleeve 39 also carries a projecting arm 46 which is pivotally attached at 4.7 to one end of a trip plunger 48. This trip plunger carries on one end the spring 49, the other end of which at 00 is mounted within the casing 1. This is known as the trip plunger load spring. The other end of this arm and its associated mechanism will be explained in connection with the setting mechanism for determining the number of revolutions per cycle of op eration for the driven mechanism.

Ring gear operating mechanism The following mechanism is provided for stopping or releasing the movement of the ring gear.

A sleeve 51 mounted on the shaft 38 turns loosely thereon. This sleeve is extended upwardly, forming a sleeve of restrictet diameter as at 52 which extends through the bearing 53 in the cover 54- of the casing. Upon the sleeve 52 is mounted the safety reset hande 55. The upper end of the sleeve is provided with a V-shaped safety notch 56. This notch receives a ii-shaped projection 57 on the safety release sleeve 58 which has a square opening 59 mounted on the square end of the shaft 33 at 60. The safety release sleeve 58 isspring pressed into looking engagement by the spring 61, the tension of which is adjusted by the threaded nut 62 mounted on the shaft 38. Upon any resistance to the further operation of the driven mechanism, the safety release sleeve 58 is driven upwardly thereby releasing the driving mechanism and preventing disastrous rupture of the parts.

The sleeve 51 carries the arm 63, which has on its end the roller 6 lthat rides upon the peripheral surface 65 of the disc 26, along the cam surface 66 of a notch and against the stopping surface 67. When this release arm 63 is in its inner position, it stops the move ment of the ring gear carrier. The angle of the face 67 is 15 to the arc of movement of roller 64 facilitating its kick out when pressure is applied; the movement of arm 63 is along the line of the resultant of these forces.

Cycle of operation setting mechanism The principle of operation of this mechanism is to have the rotation of the driving mechanism i. e. ring gear carrier, with its cam 25 operate a step-by-step mechanism to bring a releasing disc 7 0 described later known as a trip cam into position to release the trip plunger 48 thereby permitting the mechanism to function so that the ring gear carrier may be held in a stationary position while the continuously operating mechanism, such as the shaft 10, motor 10"-, gears 11, 12, 17' and 22 will continue to operate to rotate the planetary ring gear carrier which is free to move as its release arm 32 is then in inoperative position.

This will continue until the parts are adjusted for another cycle of operations and another period of movement of the driven shaft 7, as will be hereinafter described.

This cycle adjusting mechanism comprises the following A vertically-disposed shaft 68 is supported within the sleeve 69 at the bottom of the casing. Integrally formed on this shaft 68 is a trip disc 70 which is pro vided with a cutaway face 71 and a shoulder 72 communicating therewith and with the periphery of the disc. This shaft68 is furthermore provided with a ratchet 73 formed on a sleeve 73 splined thereto or integral therewith to rotate it. The ratchet 73 has a blank portion 73 for use when the index handle 97 is in off position. The ratchet is rotated by the step-by-step pawl 7 4 which is pivoted at 75 in a carrier 76 mounted for oscillation about thesleeve 73 This pawl is provided with a laterally projecting shoulder 77 which extends between ears 78 of the arm 79 which carries a roller 80 engaging the periphery of the cam 25. This arm is known as a timer feed arm. The arm is mounted for oscillation upon the sleeve 81.

The pawl 74 is broad enough to span the ratchet 73 and the ratchet 82 mounted to rotate independent of the ratchet 73. This et 7 3 towards the position where the pawl 74 can drop into a tooth thereof to actuate the ratchet 73 and its associated disc 70.

When such a movement has taken place and the disc is rotated to a point where the end of the trip plunger 48 can drop off the shoulder 72 on to the surface 71 of the disc 70, the spring 49 then transfer-s its energy to a movement of the lever 63 inwardly to engaging position with the ring gear carrier so that it will eventually engage the surface 67 of the cam 65 and stop the ring gear carrier from further movement. 7

The movement of the trip plunger 48'as it is connected at 47 to the ear 46 of the lever 40, which is loosely mounted on the shaft 38, moves that lever so that its lug 45 engages the lug 36 to actuate the lever 32 to move this roller 31 out of the depression 30 and thereby unlock the planetary gear carrier 20.

The parts are now moved into position shown in Figure 7. As the ring gear carrier is stationary, the planetary gear will transmit movement to the shaft 7.

This continues until the re-set cam 27 which is traveling with the planetary gear carrier that is now rotating about the axis of the shaft? with it until the surface 42 engages the roller 41 moving the lever 40 to its outermost position where it is maintained while it rides upon the surface 43. This permits the lever 32 to have its roller 31 rest upon the periphery of the disc 28 and to freely drop into the cutaway portion 30 under the impulse of the spring 34 when that disc comes opposite the roller 31. This is made possible by the removal of the shoulder 45 of the lever 40 from engagement with the'shoulder 36 of the lever 32 by the movement of the lever 40 to its outermost position. This further results in a backward movement'of the trip plunger 48 which detaches the holding pawl 86 to permit the re-set spring to re-set the disc 7 O in a new position so as to receive and maintain the trip plunger 48 in the position shown in Figure 6 when his permitted to return to engage the disc 7 O. This is accomplished when the roller 41 drops off of the cam face 43 along the face 44.

As the arms 32 and 63 move together normally, the entry of one into'its cam groove moves the other out of position. In the event the-driven mechanism is resisted in its operation, the connection between these two arms through the safety lock 59 and spring 61 permits of their disconnection by the safety angle of 67 which it makes with the arm 63 to throw said arm outwardly and a consequent rupture of the mechanism.

The movement of the handle connected to this safety lock, which handle is designated 55, will indicate to the operator by the movement of that handle to the out position that something is interfering with the free operation of the mechanism.

An oil gauge consisting of a gauge rod 103 is provided for indicating the height of 111- bricant in the casing. An orifice is closed by the plug 104.

In off position of the index handle 97 the pawl 74 rests on the blank part 7 3 of the ratchet 7 3, and the timer will not feed up so that the shaft 7 remains stationary as long as the index lever 97 remains in off position.

hen the'index handle 97 is in the position indicated by the word Bank the tension of the spring 95 is released and the position of the shaft 68 is such that the pawl for operating this shaft cannot engage the teeth of the ratchet wheel 73 for rotating the disc 70. In this position the shaft 7 rotates continuously. When the index handle 97 is in the position shown in Figure 1 the shaft 68 and the disc 70 are so positioned with relati on to the trip arm 48 and the other parts of the mechanism that the stoker shaft 7 is not operated.

When the index handle 97 is positioned between these two extremes, with the lug 98 engaging with any of the notches 99, the stoker operating shaft 7 has intermittent movements, the period of time between the movements depending upon the position of the index handle 97. As the index handle 97 approaches the word Off and the point on the end of the index handle approaches the word Bank, the period of time between the successive rotation of the shaft 7 is gradually diminished until the index point reaches the word Bank, at which time the stoker shaft continuously rotates. "As the index handle approaches the word Bank the time between the periods of rotation of the shaft 7 increases gradually until the handle reaches the point shown in Figure 1, at which time the stoker shaft 7 does not rotate at all.
